"Heavy duty suspension should be fitted to those vehicles asked to carry loads close to their limits over rough ground. Heavy duty shock-absorbers will also assist...Loading any roof rack too well forward will cause overloading of both roof pillars and front springs, which are not designed for this and structural failures from overloading show themselves in the form of cracks appearing in the windscreen. If you also have a winch, bull bar, power steering and air conditioning fitted, your front springs may well be pushed beyond their weight carrying limit. Overloading a vehicle’s springs will quickly result in serious structural failures in rough terrain."

"When coil springs are exchanged for higher rated units make your
selection carefully. Light-duty units will feel similar to those that
the manufacturer has fitted but will ensure longer life of the shock
absorbers, especially if they are the gas type. Medium rate springs
will improve road holding, reduce body roll and improve payload
by a small amount. Hard springs will improve off-road handling,
on-road adhesion, reduce body roll and are recommended for
vehicles with loaded roof-racks. They improve heavy payload
handling, stability and safety but may feel harsh on-road."

Given the above information it seems it is best to have Heavy duty coils and heavy duty gas shocks for off-road safari ventures. Also, after further researching it seems like the Frankenlift with the HD OME springs and OME front strut and rear OME N132L shock upgrade is the best lift kit/suspension for the KJ. The two lift kits that I am debating about are the Frankenlift and the Rusty's/OME lift. I have some questions that hopefully you can fill in the blanks for.
Rusty's
coils springs -- ? Are they Heavy Duty, Light Duty, or Medium Duty? Are they OME Springs?
I noticed a lot of guys are doing clevis lift to compensate for sag. Is this because the springs are light duty? Will the frankenlift sag too even with the heavy duty springs?
Frankenlift
Will the lift require Al's A-Arms or are they only nice to have? If required, this would increase the cost of this lift considerably.
Thanks
